Sequence and scale of changes in the terrestrial biota during the Cretaceous (based on materials from fossil resins)
Abstract Сomparative analysis of arthropod assemblages found in Cretaceous fossil resins is provided. Arthropod-bearing Cretaceous resin sites are reviewed, and a list of arthropod records… Expand
COMPUTER-AIDED DRAWING SYSTEM - SUBSTITUTE FOR CAMERA LUCIDA
The drawing system we describe consists of a microscope, digital video camera, computer with a mouse or a pen tablet, and freely available software. The system uses an overlay technology that allows… Expand

To elucidate mechanisms that underlie the profound physiological effects of the monoamine precursors 5-hydroxy-l-tryptophan (5-HTP) and l-3,4-dihydroxyphenylalanine (l-DOPA), we examined their action… Expand
Phasic Coordination between Locomotor and Respiratory Rhythms in the Mollusk Lymnaea: Transmitter-Specific Modifications
Our study using a freshwater pond snail is one of numerous works aimed at understanding the mechanism underlying the effect of the neurotransmitter level on the choice of the behavioral program. We… Expand
Frequency tuning of individual auditory receptors in female mosquitoes (Diptera, Culicidae).
The acoustic sensory organs in mosquitoes (Johnston organs) have been thoroughly studied; yet, to date, no data are available on the individual tuning properties of the numerous receptors that… Expand
Frequency organization of the Johnston’s organ in male mosquitoes (Diptera, Culicidae)
ABSTRACT The Johnston's organs (JO) of mosquitoes are the most complex mechanosensitive organs yet found in insects. Previous findings on the behavior of mosquitoes suggest that, together with… Expand
Phasic coordination between locomotor and respiratory rhythms in Lymnaea. Real behavior and computer simulation.
In the pond snail Lymnaea stagnalis, a firm phase-locked coupling of pneumostome movements to the locomotor cycle was observed during terrestrial locomotion, thus demonstrating that the coordination… Expand
Central Pattern Generators
- P. Balaban, D. Vorontsov, +8 authors M. Falikman
- Biology, Medicine

A central pattern generator (CPG) is defined as a set of neurons whose members work together to generate organized motor output activity. A round-table discussion on central pattern generators was… Expand
Monitoring of neuroactive factors released from a pattern-generating network.
To detect neuroactive factors in biological fluids, we have previously elaborated a moveable biosensor, the preparation of isolated neuron penetrated with recording microelectrode. Here, we report… Expand
